CRC32c INTEL hardware acceleration found in crypto/Kconfig

The configuration item CONFIG_CRYPTO_CRC32C_INTEL:

• prompt: CRC32c INTEL hardware acceleration
• type: tristate
• depends on: CONFIG_X86
• defined in crypto/Kconfig
• found in Linux kernels: 2.6.28–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0, 6.0+HEAD

Help text

In Intel processor with SSE4.2 supported, the processor will support CRC32C implementation using hardware accelerated CRC32 instruction. This option will create 'crc32c-intel' module, which will enable any routine to use the CRC32 instruction to gain performance compared with software implementation. Module will be crc32c-intel.
